Hi guys!
I just got here, so I don't know yet if you guys said something like this before, but I am going to share my experience with a corsair keyboard and linux/macos.
I own a Corsair K70 LUX RGB, and I've been using ckb-next for the past... 4, maybe 5 years? I also had the opportunity to try it on many different distros (ubuntu, mint, suse, arch, manjaro, elementary, and many a few others that I don't quite remember).
Choosing my main distro became a matter of "which distro can at least work with the keyboard out of the box". Because many distros that I tried the keyboard would not work. I had a fight of over a year with elementary because I could not for the love of Linux make the keyboard work consistently. I would boot the computer, and some times the keyboard just would not work. Removing and plugging the usb a few times would eventually make it work though, but it was a pain.
The important detail here is that once logged in, the keyboard would work just fine as long as ckb was running. I had this inconsistency problem only on the logging in screen.
That's when I just gave up and just started using distros where the keyboard would work out of the box.
And I give you two names: Linux Mint and Manjaro.
Those were the only ones so far that I had absolutely no problems whatsoever.
